• Compared to a stock ?bolt?, these JIMS manufactured studs allow the technician the assembly finesse required when torqueing the rocker arm shafts on the cylinder head during engine assembly
• These shafts not only improve the stock head configuration; they are a must in a performance application with increased spring pressure
